The amazing churches.
Notre Dame is full of Gothic and biblical carvings. Everywhere you look a story is told.
Saint Chapelle has the most amazing stained glass. The windows depict the whole Bible if you read them right.
The view of the Eiffel Tower from everywhere.
The detail and architecture.
The Macaroons. And Wine. And Cheese. And Bread. And Crepes.
Even the Metro signs are cool.
